Its just not good service.
CV tries harder than most but I just came back to them from FIOS after 2 years and its not any better now than it was when I left. I get disconnected from WoW servers very often where with FIOS it almost never happened. The fluctuations in quality of connection are vast especially between 6 and 10 pm, packet loss, slow downloads, etc.
As for TV, the guide is antiquated and slow whereas FIOS has a great guide which is sharp looking and very functional. I know CV is planning new things for that front but I doubt Ill be around long enough to see it since Ive started thinking about switching back.
I hope they take the company private, if they didnt already, because with the right leadership and no stockholders breathing down managements neck maybe they can truly compete.
